{"product_id":"3-55-ratio-ring-and-pinion-set-1","title":"3.55 Ratio Ring and Pinion Set","description":"The Yukon high performance ring and pinion set is engineered for GM cast iron Corvette dropout differentials, offering a 3.55 ratio for enhanced performance. This set includes an 8.20-inch ring gear diameter and a 30-spline pinion.\n\nDesigned specifically for the 1963-1979 Corvette, this ring and pinion set provides a direct fit for the specified model years. The 3.55 ratio is a popular choice for a balance between acceleration and highway cruising, making it a versatile upgrade for performance-oriented builds.\n\nTechnical notes indicate that while this set features a 30-spline pinion, earlier Corvette models from 1963 and 1964 were manufactured with a 17-spline pinion. It is crucial for owners of these specific years to confirm their existing pinion spline count before purchasing to avoid compatibility issues. This verification step ensures a smooth installation and proper function of the new differential components.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870976930104,"sku":"YG GMVET-355","price":519.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-55-ratio-ring-and-pinion-set-1","provider":"MOTORMIA","version":"1.0","type":"link"}
